With a daily yield of 3.5 million liters, the more than 30 sulfurous Aachen and Burtscheid mineral thermal springs are among the most productive mineral thermal springs in Germany. With their high content of mineral and trace elements and temperatures of up to 75°C, these springs are also among the best-known and hottest thermal springs in Central Europe.
One of these springs is the Aachen Rose Spring. From this spring, the Carolus Thermen continuously receive fresh mineral thermal water of the best quality via a pipeline. The spring is located – covered by buildings, but perfectly protected – in the middle of Aachen’s city center, in Komphausbadstraße. At the spring directly, the temperature of the water averages 47°C.
Aachen’s hot springs have been known for more than 2,000 years and are still inseparably linked to the history – and the name – of the city. For the city name Aachen can be derived both from the Old High German word “ahha” (water) and from the early medieval “Aquis grani” as well as the Latin “Aquae granni” derived from it, which in turn refers back to the Celtic god of healing Grannus.
After the Celts and Germanic tribes, it was above all the Romans who discovered the healing and soothing effects of the Aachen springs and celebrated a comprehensive bathing culture in spacious, luxurious thermal baths. Even then, bathing in the warm mineral thermal water was not only for health reasons. It was “good manners” to meet in the baths and also to discuss important business there. Under Charlemagne – who was so convinced of the healing effects of the hot springs that he declared Aachen his favorite palace at the end of the eighth century – the Aachen baths experienced a renewed heyday.
Thanks to the work of the Belgian spa doctor François Blondel, Aachen then advanced to become one of the leading spas from the 17th century onwards. Prominent bathers from all over Europe – such as Tsar Peter the Great, the composer Georg Friedrich Händel, the Prussian King Frederick the Great, King Gustav III of Sweden, Empress Joséphine, Napoleon’s wife, and even Casanova – used the Aachen and Burtscheid bathhouses to alleviate their illnesses.
To this day, Aachen is a well-known and well-visited spa town, where the two-thousand-year-old bathing tradition lives on and has been enriched by the Carolus Thermen, which opened in 2001.
The mineral thermal water of Bad Aachen can have a supporting effect on the following complaints:
Rheumatic diseases
Wear and tear diseases
Inflammatory and degenerative diseases of the musculoskeletal system
Consequences of accidents and operations
Gout and osteoporosis
Dermatoses
The main components of the mineral thermal water of the Rose Spring are:
Sodium (Na), Chloride (Cl) and Hydrogen Carbonate (HCO3).
Time to take a deep breath: the warm, moist, salty steam increases your sense of well-being.
Strokkur means “butter churn” in German and is the name of an Icelandic geyser that ejects a fountain of water and steam up to 35 metres high at regular intervals.
Inspired by the special atmosphere surrounding this geyser, our brine steam bath “Strokkur” enchants not only with its imaginative design with backlit glass walls, a starry sky, two decorative steam chimneys, a small artificial geyser and individually controllable steam bursts. Because thanks to the concentrated brine, which is distributed throughout the room via ultrasound nebulisation, a stay in this steam bath is as healthy and invigorating as a walk on the North Sea beach.
